Title: A method of and apparatus for effecting thermal processes with finely granular or pulverulent substances
IPC: C10B49/16
Filed: 1952-02-20
Abstract: <PICT:0694847/III/1> The parent process is improved in that provision is made for a more uniform heating or cooling of the heat carrier, this being achieved by flowing the carrier downwardly between two vertical or inclined walls of the heating or cooling chamber and introducing the heating or cooling gases into the mass of the carrier through both walls or on both sides from below the walls. The Figure shows a heating chamber 1 of cylindrical shape which contains a hollow, concentrically mounted insert 2, the conical top of which serves to distribute the particles of heat carrier descending from a feed hopper 7 evenly into the annular space around the insert.  The chamber 1 is surrounded by a duct 3 supplied with heating gas from a pipe 4, part of the gas passing under the downward extensions 16 of the chamber walls into the outer periphery of the heat carrier mass whilst the remainder flows through radial ducts 5 into a conical hood 10 and thence into the insert 2 from which it flows out beneath the edges of the insert into the inner periphery of the mass.  The gases pass up through the heat carrier and discharge through an outlet pipe 6. The heated material passes down through an annular duct 11 into the reaction chamber 12, the duct 11 being supplied with steam from a pipe 18 to prevent the reaction gases from entering the heating chamber.
